Decimal floating point numbers - first draft This is according to FB4 roadmap - enhancement of precision of calculations in firebird. You can read about decfloat datatype here: https://www.toadworld.com/platforms/ibmdb2/w/wiki/7700.decfloat-overview IBM's library decNumber (has ICU license) http://speleotrove.com/decimal/decnumber.html is used in out implementation.
What's done: - Added new datatypes: DECFLOAT(16) and DECFLOAT(34), using 64/128 bits for numbers representation. - It can be used in all calculations, including various aggregates, power and logarithm, but missing trigonometry. - DecFloats are supported in network protocol. What's missing: - Use of decimal float in sort operations - Control over rounding modes and exception raise rules (low-level support is included). ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
